Wardynski consulted with lawmakers earlier in the week about the first draft of the bill, which, in a surprise move, Republicans substituted a 27-page school choice bill for, drawing fire from Democrats and some educators.

Both bodies of the Alabama Legislature passed House Bill 84 on Thursday, which will allow students who attend failing schools to transfer to private, parochial or other public schools through taxpayer-funded vouchers. Gov. Robert Bentley (R) is expected to sign the bill into law on Tuesday.

"Legislators have created a great uncertainty," said Wardynski. "My guess is that we will have some school closings."
